eSense Sensors

PHT's exclusive eSense family of wirelessly integrated measurement devices (e.g. spirometers, glucometers, activity monitors) allow sponsors to collect precise physiological objective data in conjunction with subjective diary self-reports. eSense prevents fake measurements and allows researchers to ask new questions, such as timestamped pain scores vs. actual activity level, that aren't possible using paper diaries.

Gain a Complete Sense of the Subjects in Your Trial

Sometimes, subjective information is not enough to show efficacy. Certain trials require sponsors prove treatment benefit based on other PRO measures such as Peak Expiratory Flow (PEF) scores, blood sugar level and activity. eSense ensures this data is timestamped, attributable and reliable.

Truly Objective Data

eSense captures objective physiological measurements reliably by preventing subjects from entering data manually into the LogPad - thereby eliminating invented data, temporal uncertainty, user error and transcription error. If the data exists, you can be certain that subject used the measurement device appropriately, per the terms of the study protocol.

Taking a Deep (Wireless) Breath

Together, PHT and nSpire Health developed the first wirelessly integrated ePRO solution ever used in a clinical trial, the PHT eSense PiKo^®. Today, wirelessly integrated PEF meters are quickly becoming the gold standard in asthma research. Review PHT Insights (Q2, 2005) for a day-in-the-life comparison of two subjects, one using the eSense PiKo and one using paper, in a typical asthma trial.

Why Not Bluetooth?

PHT supports Bluetooth as well as eSense integration, thereby offering the most flexibility for study sponsors. eSense is a unique to PHT. It is a low-power wireless radio protocol, similar to the ZigBee standard, which offers several advantages over Bluetooth for certain trials and requirements.

Automatic and wireless transmission of data to the LogPad within 15 feet
Convenient "Store and Forward" capabilities to allow independent use of the measurement device and eDiary throughout the day
Long-lasting battery life
Secure data transmission and reliable device/LogPad pairing
Wider variety of devices supported (i.e. any device capable of outputting data through a serial interface)
